In the above example when integer 15 is on the input INP the OUT1 has a value
=1, OUT2 has a value =2, OUT3 has a value =4 and OUT4 has a value =8. The
sum of these OUTx is equal to 1 + 2 + 4 + 8 = 15.
This follows the general formulae: The sum of the values of all OUTx = 2
x-1
where
1≤x≤16 will be equal to the integer value on the input INP.
The Integer to Boolean 16 conversion function (IB16) will transfer an integer with
a value between 0 to 65535 connected to the input INP to a combination of
activated outputs OUTx where 1≤x≤16. The sum of the values of all OUTx will
then be equal to the integer on input INP. The values of the different OUTx are
according to the table below. When an OUTx is not activated, its value is 0.
When all OUTx where 1≤x≤16 are activated that is = Boolean 1 it corresponds to
that integer 65535 is connected to input INP. The IB16 function is designed for
receiving the integer input locally. If the BLOCK input is activated, it will freeze
the logical outputs at the last value.
Values of each of the different OUTx from function block IB16 for 1≤x≤16.
The sum of the value on each INx corresponds to the integer presented on the
output OUT on the function block IB16.
Name of OUTx
Type Description Value when
activated
Value when
deactivated
OUT1 BOOLEAN Output 1 1 0
OUT2 BOOLEAN Output 2 2 0
OUT3 BOOLEAN Output 3 4 0
OUT4 BOOLEAN Output 4 8 0
OUT5 BOOLEAN Output 5 16 0
OUT6 BOOLEAN Output 6 32 0
OUT7 BOOLEAN Output 7 64 0
OUT8 BOOLEAN Output 8 128 0
OUT9 BOOLEAN Output 9 256 0
OUT10 BOOLEAN Output 10 512 0
OUT11 BOOLEAN Output 11 1024 0
OUT12 BOOLEAN Output 12 2048 0
OUT13 BOOLEAN Output 13 4096 0
OUT14 BOOLEAN Output 14 8192 0
OUT15 BOOLEAN Output 15 16384 0
OUT16 BOOLEAN Output 16 32768 0
The sum of the numbers in column “Value when activated” when all OUTx (where
x = 1 to 16) are active that is=1; is 65535. 65535 is the highest integer that can be
converted by the IB16 function block.
